Are you talking about just the bottom end seals or the top end as well? Because there will be an obvious difference in the intake manifold seals due to the sc setup.
There's also a pretty big price difference between the 2 seal kits. I've been quoted $270 for a ae92 4age seal kit and $400 for a aw11 4agze.
There's gotta be something else in that extra $130 that isn't in the GE kit.
